ing had to the accompanyin drawingsi 10 which form a part of' this specification;-- Thisinvention relates to doors or swinging closure members,and my improvement is directed to means whereby a device of this character'is capable of opening infeitherdirectiomit being provided for thispurpose" with engaging means at each side jwhich serve both as'hingesz and: locks, having the ties.-. 7 v For thi's' purposethe 'pivotsof the hinges are 'retractibl'e whereby the hinge portions that are attached to the closure member become free and thereupon the closure vmemcharacteristics of both these instrumentaliber can be swung openusing the opposite. hinges as its Since the hinges atthe opposite sides {of the door of closure member are similarly operable it isinnnateri'al whether the hinge pivots be retracted from the hinges at one side for "the other of the "door," because when the hinge pivots are removed at one side then theghin'ges at the oppositeffside of ,the door are those upon which the door hangs in itsswinging movement, in or ent. 1

In carrying out my'invention cause the 7 door or other closure device equipped therei with to be mounted on hinges at both its side ends, but in each'instance the hinge pivots are retra'ctible to also serve the purpose of;

These pi-vot f y i r bolts operate-in guides 7 and, at theirinner- 0 lwith b-ars -.8, 9,' that, at'their'opposite-endsi Q are mounted by pivots 10, 11', upon a. plate 12, which i's-i nserted within an'd' securedto;-

,7 7 pins being entered within oppositely angled;

upper and lowerslots 14 formed in a plate" 15-that is 'slidable horizontally in guideslfi carried by' the fiXed-iplate '12. "Since thevj slots 14 have "outwardly. converged relation,-

effect ofsliding th'e plate 16, outwardly will be to retract thejpivot bolts; for re engage j is cl0S l,- O, I it An operating banana??- is bar-Pied? post '18 that" is mountedon'the plate 12; and

which. is normally urged upwardly by" a casing, stop finger 28: is thereby carried into endwise abutting relation with finger piece 29, preventing the extension-of the bolts while the door'remainsopen, thus leaving theopendoor at all times capable of closure.

But ifthe detent bar 22 should be depressed manually, as-by pressing downwardly upon its upper end 22 then'the handle can be (turned to extend the bolts.

The pivot-bolts 30, 31 shown in Fig. 1- at the other side of the door, may be provided with identical.associated'parts and me2hanism as have'been described in connection with the bolts 2 and 3. Those parts and But Ihave also shown, in-conncction with the bolts 30', 31 a modified form of control mechanism wherein'thebars 8, 9 are con nected,by toggle arms 32, 32, with linl: 38 that is pivoted to the free end o't'an arm 34 carriedv by the handle post 18. The pivotal connection 32 for arms 32 is shown as slidable in a slot 32 provided thereforin plate 12. A pawl 35 pivoted at 36 to plate 12, is mounted on the detent bar 22,-which engages by aslot-22 ;th'erein with a pinn: carried by bar 8,1to co-act-therewith-the pawl35.

being held upwardly upon said arm34when the toggle is expanded; to extend the pivotbolts. But when the-toggle is contracted, thereby retractingthe bolts, the pawl '35, uponthe withdrawal ofdetent 22 which occurs While the door is opening, is moved into horizontal abutting relatlonwlth the arm 34, against the tension of spring 27-, and thus holdsthe pivot-bolts retracted fordoor closure purposes. I I

Normally it is desirable that the bolting means at one side only of the door are to be capable of OPQIfltiOIlySOilllfil]'lf'tl'le handle at one sidev be turnedto release its pivot-bolts the otherhandle will be incapable-of similar operation. For this purposel have shown horizontal. bar .36 i extended inwardly from toggle. arms32, isshown" as extendingrearward-1y from the-pi-vot 82 the clearancebetween the opposed ends bars 3 6-, being mentof oneof the bars at a time, Therefore, when one of the handles 181has been turned to retract its pivot-bolts the bar 36 or 37 will come into abutting relation with the other of said bars, and thereby serve as a stop to prevent the bolt withdrawing operation of the other handle.

It is a purposewithmy invention that the door shall open away from the side at which the handle is placed, thisibeingia useful pro 1 vision for fire and panic doors, and therefore I have mounted the handles respectivelyat opposite sides of-the door, andprovided thez respective casing engaging means insuch manner-that the door will open, at-each side; i
